After transmigrating to a new world, Jiang Qi goes to an amusement park with his friends. At the entrance to Tropical Land, they meet Shinichi Kudo, and Jiang Qi realizes with a start that he's transmigrated into a manga.
Before he can remember the plot, his friend, an avid detective fan, drags him over to ask Shinichi Kudo for an autograph. By pure chance, they witness Gin club Shinichi Kudo over the head.
At that moment, the familiar BGM starts playing, and Jiang Qi remembers the opening of that series that gets a theatrical movie every year.
Unfortunately, he remembers too late. Gin has seen him, too, so he gets treated to a dose of APTX 4869.
Jiang Qi has an immortal body, so he thinks taking a dose of poison won't matter. He can't die, after all.
But when he wakes up from his coma, he jolts upright, close to death: How did he end up shrinking along with Shinichi Kudo?!
It's very interesting. Kudos to the author😊
Is the protagonist a boy or a girl? Should I use the girl's name?
Very good, come on, come on
